Russ, Elliott, Kenny and all:

This might sound glib, but I believe that setting landuse=forest on a (multi)polygon which is land use forest is correct.  Yes, I have notice that mapnik rendering has changed over the years so that other 2-D objects which occupy the same space may yield unexpected results.  I believe this is because of the ordering of the rendering of these multiple objects, acting as “layers” in the final visual representation.  Whatever changes have been make to mapnik in how it orders lands rendering (or, specifically, landuse=forest) seems to be the culprit here.  While I might have gotten used to an older rendering, the newer rendering is simply a different way of seeing what is hopefully accurately tagged areas.

In short, tag correctly.  If the renderer renders in an unpleasing way, see if it is because there are multiple objects on top of one another, and examine whether that is the right approach — it likely is not, but it may be, too.  THEN we might discuss if the mapnik renderer has problems.
